Bug#665809: libdate-manip-perl: ParseDate breaks on non-existing times during DST change

[Andy Spiegl]

Package: libdate-manip-perl
Version: 6.11-1
Severity: normal


Date::Manip does not handle the case correctly where a specified time
lies in a non-existing gap, e.g. here in Germany between 2am and 3am
when the time is skipping one hour.

Try this to reproduce the bug:

---8<----8<-----8<-----8<-----8<-----8<-----8<---
#!/usr/bin/perl

use strict; use warnings;

use Date::Manip;

&Date_Init();

my $d = ParseDate("2012-03-25 at 02:11");

---8<----8<-----8<-----8<-----8<-----8<-----8<---
